Sprocket - 45 Tooth

Receive high quality products from JT sprockets. I have and 09 G 650 GS and the top speed is electronically limited so you can't get around that but at 90 mph and anywhere above 60 the bike feels so much more composed. I put 90 because if you own one of these machines you know how hard the bike feels like it's working from that point on. I noticed no noticeable loss of speed on take off and every single gear feels better . If you consistently ride at speeds over 60 this with the 17 tooth front sprocket will make you fall back in love with you GS 650 again. It's really such a game changer . I ride with a backpack a lot she's around 120 pounds and we do light off road stuff and plenty of trips over to the coast and that fatigue from just the bike at 85&90 had me ready to get rid of the bike. Which I know I would've missed it even though I'm planning on just upsizing to the GS 800 model soon anyway. But just the overall capabilities of the 650 with the awesome fuel milage and just the almost perfect balance with the bike I haven't rode another adventure bike it that displacement that handles on and off road like this bike does and again I noticed no difference in performance. Now all that said I do not ride my bike loaded down with saddlebags or gear . I keep it light just my passenger backpack and a backpack on her with drinks and snacks or lunch whatever so a little over 400 pounds and the motorcycle is still very quick to 100 and no issues in sugar sand or small hills we have off road in Florida I couldn't tell you about mud or muck because my mainly pavement princess is well used I push the bike often and am way ahead of the maintenance curve and keep it clean well lubed and all fluids changed more often than the owners manual recommendations.

I went with 16/45 and couldn't be happier.I can now cruise comfortably at 80mph

Brought the rpm's down at highway speeds, much less vibration. Runs very smooth at 70 mph. Great product!
